Actually Mea... I don't know! I think it might have a shallow long keel or even shallow twin keels. And yes, they are both supposed to be resting on mud, not in the water. I think I messed up the top profile of that boat, but decided that since it obviously had lumpy stuff on the deck and I couldn't work out where the bow is/was, good enough would have to do! When I was a cruising sailor (lol), we often cleaned our hull by beaching the boat at low tide and scrubbing her off. Standing upright leaning against against mooring poles was quite a luxury. Mind you... These particular poles don't look all that robust. I wouldn't want to trust the weight of my boat on them. Val or Stoney will probably put me straight.

You are correct Linley, the boat sitting down in the mud may have a shallow trunked swing keel, or be sitting on bilge keels. The fin keel boat would be slightly leaning and secured against the pilings.

To get tides high enough to do this in Canada, you'd have to be on the ocean coast. I like it.

Query: Ocean coast??? but Canada is flanked by two oceans... the Pacific and the Atlantic...? Not sure what you mean. We laid down on the hull along the North of Australia because slips and cradles were few and far between. The tidal range was extensive but we had to watch out for crocodiles! For those who aren't in the boating world... Hulls collect seaweed and barnacle growth which impedes the progress of the vessel through the water. So this growth has to be scrubbed off. The warmer the water, the more vigorous the growth. I have known yachtees who have accidentally beached themselves on these tides, and who have pretended to be scrubbing off till the next tide comes in.

The reason I said 'ocean coast', is we have seen some foreign boats waiting for the tide to drop while in the great lakes! Which at best you might see a foot.... it would be a long....long....long....wait!

The Bay of Fundy however is a different story entirely. They have tremendous tides. When the tide was out we used to go and play mudball on the flats. Had to watch your timing though....we had to run for it one time, nothing like a fast moving wall of water to inspire a good sprint back to shore! Priceless!
